In short

Ask ten questions before you sign: who installs the wall; who chooses the plants for your light; how it is watered and drained; what it is fixed to; whether you can see a sample or mock-up first; how fire safety is covered; what the maintenance contract includes and how fast they respond; who replaces plants that fail; what you get at handover; and which similar projects you can see or ask about.

Ten questions, and what a good answer sounds like

QuestionA good answer
Who installs it?Our own crews, with a supervisor on site
Who chooses the plants?A horticulturist, for your light, air-conditioning and the way the space is used
How is it watered and drained?Drip irrigation on an automatic controller, with a drain and an overflow plan
What is it fixed to?Lightweight panels or frames on brackets anchored to the structure, shown in a detail
Can we see it first?A sample, and a full-size mock-up for large or unusual walls
What about fire?Fire-retardant materials where needed, with test reports
What does maintenance include?Visit frequency, response time and a service log after every visit, in writing
Who replaces plants that fail?Replacements as agreed in the contract, stated up front
What do we get at handover?Fixing details, a plant list, care instructions and the warranty terms
Can we see similar work?Projects of similar size and type, and references on request

Builder or reseller?

Some green wall firms sell a system and subcontract the installation and the care. That can work, but ask who will actually be on your site, and who answers the phone when a plant dies in month eight.

A firm with its own crews and gardeners in your city can usually respond faster, and it owns the result from design to care.

The plants decide whether it lasts

Most indoor walls that fail do so because the plants do not suit the light. Ask who chooses the palette and how, and whether they have checked the light where the wall will go.

Outdoors, ask about sun, wind and water: hard water and a hot west-facing wall need different choices.

Water, drainage and power are not extras

A living wall needs a water point, a drain and power for the irrigation controller. If a quote does not mention them, ask who provides them. It is often the fit-out contractor, and it has to be planned early.

See it before you buy it

For a feature wall, a sample of the panel and plants is enough. For a large or unusual wall, ask for a full-size mock-up; a firm that offers one is confident about what it builds.

Read the maintenance contract

The cheapest quote often leaves out the care. Ask how often gardeners visit, how fast they respond to a problem, who pays for replacement plants and how you will know what was done. A service log after every visit is a good sign.

Questions

Is a vertical garden company the same as a landscaping company?

Not always. Many landscapers build gardens but not walls; green walls need panel, irrigation and indoor-plant skills. Some firms, like ours, do both.

Should we buy or rent a green wall?

Buy if you want to own it, and add an annual maintenance contract. Rent if you want one monthly fee with care included; we offer natural green walls on rental.

What should a green wall quote include?

The panel or fixing system, the plants, irrigation and the controller, installation, and the care terms. Water, drain and power are often by others, so check who provides them.

How long does a green wall take to install?

A small indoor wall can go up in a few days once the materials arrive. Large or outdoor walls take longer, especially when a mock-up is approved first.
